2025年1月2日 · Currently, as of my knowledge, IBM's quantum composer does not allow you to reverse the order of the qubits, but Qiskit does at least when drawing the circuit. If you prefer the quantum composer you can copy the code that is generated and paste into a Jupyter Notebook/python file, adding qc.draw(output='mpl', reverse_bits=True) to reverse the bits.

2020年12月5日 · This is run on ibm_16_melbourne. The compiled circuit is pretty strange, see the second screenshot attached, where the number of qubits does not seem to match (q0-q3, q8-q14 are not involved), and I am not sure if the desired property (described above) is respected.

2020年5月4日 · I am interested in the execution time of quantum gates on IBM's $15$-qubits Melbourne computer. Is there any information regarding this? Is there any information regarding this? After searching for a while I have only managed to find the times of the CNOT gates here , but unfortunately, no information for other quantum operations.

2021年8月6日 · This file from the archived repository ibmq-device-information associates backend name ibmqx2 with display name IBM Q 5 Yorktown. The IBMQ systems page does list a 5 qubit Yorktown device, but under the name ibmq_5_yorktown. This backend is also available via ibmq/open/main, but is not listed by provider.backends().

2025年1月30日 · IBM describes its q-sphere visualization as:. Beginning at the north pole of the q-sphere and progressing southward, each successive latitude has basis states with a greater number of ones; the latitude of a basis state is determined by …

2021年3月17日 · You can see the backends you can access directly on the IBM Quantum tools by going on the top left corner of the page, click and then go to Quantum Services, and click on "Yours". Now, via Qiskit, you can do this, for example to access the open provider and get the backend ibmq_athens :
